**Suppresion of LH, thickening of cervical mucous, making the lining of the uterus atrophic, influence capacitation**
What is capacitation?
the ability of a sperm to penetrate an ovum

bleed all the time
If a women is on OCPs, what should her cervical mucous look like?
Thick and tacky, question her if it is thin and stringy
What are the pharmacologic effects of progestins in combination OCs?
inhibit ovulation by suppressing HPO function, modify mid-cycle surges of LH/FSH, diminish ovarian hormone production, produce endometrial changes unfavorable for ovum implantation, thicken cervical mucus to impede sperm transit, inhibit sperm action

Reducing the dose of the estrogen and progestin components and new, more selective progestins. Goal for lowered doses is a pill that does not compromise bleeding profiles
Why are all combo OCPs anti-androgenic in the way they behave?
The oral estrogen increases the sex hormone binding globulin (SHBG) and this binds the testosterone that causes acne
What is causing a breakout from the pill?
the type of PROGESTIN, so change that to a less androgenic pill
